$Combined probability is $ \frac{1}{4} \times \frac{2}{11} = \frac{2}{44} = \frac{1}{22} $.$

Total balls = 3 + 4 + 5 = 12.
Probability of first red = $ \frac{3}{12} = \frac{1}{4} $.
Probability of second red = $ \frac{2}{11} $.
#### $\frac{1}{22}$Question: An AI ethics investigator is analyzing a dataset containing 84 biased algorithm records and 126 unbiased records. What is the greatest common factor of 84 and 126?
Solution: To find the greatest common factor (GCF) of 84 and 126, factor both numbers:
$84 = 2^2 \times 3 \times 7$
